From: Amit Pundir <amit.pun...@linaro.org>
Fix redundant "buffer->private_flags & ION_PRIV_FLAG_SHRINKER_FREE"
checks in if(!cached ...) condition block.
The previous patch, "ion: Handle the memory mapping correctly on
x86", is broken on android-3.18+ kernels. It conflicts with
upstream commit commit 53a91c68fa7b ("staging: ion: Add private
buffer flag to skip page pooling on free"), and breaks the
ION_PRIV_FLAG_SHRINKER_FREE private flag check logic.
